I don't exactially get the question, but I think you mean the Br 4 shots to the head for a kill thing. And yes that does work.
Press the right trigger four times
Halo 5 will most likely follow the story line of Halo 3/Halo 4.
there is no halo 4 because it is a trilogy. halo 3 was the end of the series.
Yes, HALO 3 ODST and HALO REACH have been made
yeah, halo 3, halo 3 odst, halo reach and soon halo 4
Halo 4 is not out yet and no ps3 will never have any halo games.
yes, he never dies in halo 3 so he will be alive (and there) in halo 4
Halo 4 won't come out, get it in your heads. Only Halo 3: Odst is coming out on 2009. Halo 3 is last of the Full game halo (series)
yes there is much more to do than halo 3
There is no Halo 4, and will be none, however... I think you are referring to Halo 3: ODST. If that is the case, then you can acquire recon armor by completing all of the Vidmaster Challenges in both Halo 3, and Halo 3:ODST.
After Halo 3 there was halo wars, halo 3 ODST, and Halo reach. A new company (not Bungie) will be making a Halo 4 and rumor has it there will be a remake of Halo Combat Evolved.
The names of all the Halo games are (in order): Halo: Combat Evolved, Halo 2, Halo 3, Halo Wars, Halo 3 ODST, Halo Reach, Halo: Combat Evolved Anniversary, and Halo 4. In chronological order: Halo: Wars Halo: Reach Halo: Combat Evolved/Anniversary Halo 2 Halo 3: ODST Halo 3 Halo 4
